Lead = dead
You\'d better believe lead is dangerous! It\'s only dangerous however, if it gets in your body. Therefore do not ever, no matter how hungry you are, eat your miniatures!
Seriously, it is unlikely you will ever get enough lead inside you to do any serious harm, providing you take sensible precautions. Normal handling IMO is ok. providing you dont eat or suck the damn thing. However... if you regualarly use needle files, dremels, wire brushes, blunt edges of scalpels etc. You will create lead dust which will get on your fingers and settle on the floor. This can be a major problem. At my peaks of creativity, the floor around me changes colour when I am prepping models and this is metal dust. (Not necessarily lead, \'cos MOST modern figs are lead free). It is inadvisable therefore to eat, without washing your hands, or let small children/pets into the area.
The evil thing about lead is that your body will not flush it out, it simply accumulates until it reaches a dangerous/lethal level. As usual, common sense rules apply.
As a matter of interest, certain decadent ancient Romans would sprinkle powdered lead into their wine as it heightened the effect of the alcohol. Speeded up their demise as well.:|~
